Like I said, I have the choice between a 40 breeder and a 75 gallon tank. The 40 breeder with corner internal overflow, sump (20 long),stand, plumbing, and a 4ft (4 bulb) t5 h/o lighting fixture is going to run me 175 plus my aqua c remora hob skimmer. I am also looking at a 75 Aga, center internal overflow,all of the sand, some clean up crew, 8 bulb current usa t5 Ho lighting, all the plumbing, 16 gal sump, digital timers, mag float cleaner, 3 5 gallon jugs, food, and some other little extras. I am currently running a 45 tall, and it is not drilled, so that is why I am upgrading. The 40 seems like a great deal, but I dont really want to down grade size and want something much larger in the future. The 75 is going to be much more expensive setting up, but it will be larger and hopefully keep my ambitions at bay lol. Btw the 75 includes a brand new in sump skimmer that is a turbo flotor multi sl, while the 40 includes a coralife super skimmer 65 gal. Both include return pumps, and the 75 includes an extra 750 gal rated pump as well.
